WINDOW FOR LOCOMOTIVE-CABS. 80c.

SPECIFICATION forming part of Letters Patent N 0. 632,264, dated September 5, 1899.

Application filed October 13,1898. Serial No. 693,463. (No model.)

To aZZ whom it may concern.-

Be it known that I, SARAH HARMON, of Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful WVindow for Locomotives and other Purposes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 shows a perspective view of my window from the interior of a locomotivecab. Fig. 2shows in perspective the window complete ready to be fastened to a cab of a locomotive. Fig. 3 shows a longitudinal section of a part of my Window and the manner in which a sheet-iron tube three feet long and eight inches in diameter at one end and twelve inches at the other is made fast to my window-frame.

It has been proposed to make various kinds of windows employing glass to prevent rain, snow, hail, and sparks from striking a locomotive-engineer in the face, but none has yet been employed in practice, for the reason that the glass being directly in proximity to the rain, snow, hail, and steam it was rendered thereby translucent at once. Various methods and means have been employed to heat the glass so that it would melt or dry up the rain, snow, or steam, and thereby keep the glass transparent. None of these windows as yet have been useful in practice, because in a storm the glass has not been kept transparent by any of these heating devices. This invention is not upon such principles, although heat may be used, if it should be needed for any purpose. It will be seen that by the construction of this window no heat is needed to keep the glass clear, for the glass is protected by the tube and is not in direct proximity to the snow, rain, hail, and steam, and therefore is not covered or rendered translucent thereby. Therefore myinvention consists in a window comprising the tube or projection A, eight inches at one end and twelveinches at the other and three feet long, made fast to the frame D, as is shown in section in Fig. 3. On the frame D are shown the slideways E, in which the sash B is mounted. In the sash B is a pane of glass 0.

The knob F shown on the sash B is to open the window by sliding the sash B in the slideways E.

Fig. 2 shows the window complete.

Fig. 1 shows in perspective a portion of the protect the glass from the snow, rain, sparks,

hail, and dust when the windowis shut or the sash B is slid over the innermost end of thetube A. The tube being about eight inches in diameter at the innermost end and about twelve inches in diameter at the outer end and three feet long affords a good view of the track by day, and in the night by aid of the headlight of a locomotive it acts like a telescope in keeping shadows from interfering with a perfect vision, While its projecting walls three feet outward from the cab-wall protect not only the glass from the rain, snow, hail, and steam when the window is shut, but protects the engineer from being struck in the face by rain, snow, hail, and sparks, Whether the window is open or not.

To prevent dust and cinders from collecting in the tube A, a slot G (shown in Figs. 1 and 3) is made nearly the length of the tube, through which a cinder may fall out if it happens to fall into the outer end of the tube.

Two windows like the'one shown in Fig. 2

are placed in a cab. One window is placed on each side of the cab, so that the engineer and fireman may bothsee together.

Having fully disclosed my invention, I claim as follows:

1. In combination, a locomotive comprising a cab; a tube or projection extending outward from the wall of said cab, said projection having a slot or opening'therein to prevent the accumulation of snow and dustin said projection; a Window comprising a pane of glass situated at the innermost end of said projection, to be protected against rain, snow and steam, by said projection while said window is closed, or said glass is over the innermost end of said tube or projection.

2. A locomotive comprising a cab; a win- (low-pane of glass; a tube projecting outward from the said glass and walls of the cab to protect the glass from rain, snow, and steam when the glass is over the innermost .end of the tnbe,and to protect the engineer from hail, sparks, Wind, snow and min when the glass is removed from the innermost end of the tube, and to aid the vision of the engineer to watch the rails by its telescopic action by night and by keeping shadows of objects be- 10 side the track from obstructing his vision upon the rails.
